Purpose: To observe the regulative effect of acupoint application of abnormai lipid metabolism in type Ⅱ diabetes. Methods: Thirty patients with type Ⅱ diabetes were treated by acupoint application and routine hypoglycemic agents. Meanwhile, another 30 patients with type Ⅱ diabetes were treated by routine hypoglycemic agents only. A difference in the blood-lipid level between pretreatment and post-treatment was observed in the two groups. Results: Differences in cholesterol,triglyceride, low-density lipoprotein and high-density lipoprotein between pre-treatment and posttreatment in treatment group were significantly different from those in control group(P＜0.01).Conclusion: Acupoint application has a good lowering effect on high blood lipid and can effectively alleviate the disorder of lipid metabolism in diabetics.

Objective To compare the mandibular advancement appliance(MAA) with mandibular advancement and left-leaning appliance (MALA) in the treatment of mild or moderate obstructive sleep ap-nea-hypopnea syndrome (OSAHS). Methods Twenty-two cases of mild or moderate OSAHS were treated with MAA, and 19 cases with MALA. After 1-3 months, they were examined again with Epworth score and polysonmography (PSG). Results After 1-3 months of the MAA or MALA treatment, the Epworth score was improved evidently. The apnea -hypopnea index, max apnea time, mean apnea time, oxygen desaturatian index, and the longest time of oxygen desaturation were all lowered after the treatment, and the lowest SaO2 and the mean SaO2 were higher after the treatment. The differences were all distinctive (P<0.05 or<0.01). When patients treated with MAA were compared with those treated with MALA,only the max apnea time [(35.5±6.9),(31.3±6.0) s, respectively] and the longest time of oxygen desaturation [ (41.0±18.9), (29.9±9.3) s, respectively] had significant difference. Conclusion MALA may be helpful for shortening max apnea time and the longest time of oxygen desaturation, thus MAA is an effective alternative to patients of OSAHS. Further research should be done.

AIM:To establish a simple and accurate HPLC method for quality evaluation and determination of 8 active constituents, i.e. Danshensu, Protocatechualdehyde,rosmarinic acid,Salvianolic acid B, Dihydrotanshinone, Cryptotanshinone, Tanshinone Ⅰand Tanshinone ⅡA in Radix Salviae Miltiorrhizae, at the same time, in order to study the correlations of the contents of the 8 constituents. METHODS: Detected at 286 nm, analytes were separated on a ODS C_ 18 column(150 mm?4.6 mm, 10 ?m) eluted gradually with methanol and 1% tetrafuran in 1% formic acid water solution(3∶97)on the increasement of methanol from 3% to 70% in the whole analysis. After determination, SPSS 13.0 software was used to calculate the correlation between the 8 constituents. RESULTS: Under the above conditions, HPLC method was constructed to quantify 8 constituents,and their correlation coefficients were calculated. CONCLUSION: The result shows that the contents of the 8 constituents in Salvia miltiorrhiza Bge. vary greatly from different origins; and there are significant correlations between the contents of hydrophilic constituents such as Salvianolic acid B,Danshensu,rosmarinic acid, so do hydrophobic constituents like Cryptotanshinone,Tanshinone Ⅰ,Tanshinone ⅡA,but there is no correlation between the hydrophilic constituents and hydrophobic constituents.

Objective To explore the application of PBL in dermatology and venereology teaching. Method According to random principle, 120 students were divided into experimental group and control group (60 students per group). The experimental group received PBL, and the control group received tradi-tional teaching. The teaching contents included systemic lupus erythematosus, pemphigus, psoriasis, syphilis. The course needed 16 periods totally . the traditional teaching group applied 8 classes extensive class teaching and 8 classes clinical trainee, and the PBL teaching group implemented case-based teaching 4 hours each time. Teaching satisfaction evaluation and test scores would be analyzed at the end of the semester. SPSS 17.0 was used for t test. Results The teaching satisfaction (contains professional values and ethics, communication skills, clinical skills, community health and health systems, information management, critical mind and research, etc.) of experimental group was higher than control group (P<0.05); The test scores of experimental group was higher than control group (P<0.05), especially in total score of theoretical examina-tion, comprehension and application. The difference mainly came from PBL teaching (P<0.05). Conclusion PBL is conductive not only to the comprehension and application of knowledge but to training the students' abilities of independent learning.

Objective:To observe the effects of acupuncture and moxibustion on interleukin(IL)-9/IL-9 receptor(IL-9R)in the colon tissue of rats with ulcerative colitis(UC)and investigate the protective mechanism of acupuncture and moxibustion on the intestinal mucosal barrier in UC rats. Methods:Male Sprague-Dawley rats were randomly divided into a normal control(NC)group and a modeling group.UC models were prepared by giving 4%dextran sulfate sodium(DSS)water for 7 d.After the successful construction of the UC rat model,the modeling group was randomly divided into a UC group,a herb-insulated moxibustion(HM)group,and an electroacupuncture(EA)group.HM and EA interventions at bilateral Tianshu(ST25)were performed once a day for 7 d.Hematoxylin-eosin(HE)staining was used to observe the histopathological changes in the colon.The serum concentrations of IL-9,IL-6,IL-1β,and hemoglobin-H(HbH)were determined by enzyme-linked immunosorbent assay.The protein expression levels of IL-9,IL-9R,claudin-2,zonula occludens-1(ZO-1),and occludin in the colon tissue were measured by Western blotting or immuno-histochemistry.Immunofluorescence was used to detect the co-expression of PU.1 and CD4 with the IL-9 protein. Results:Compared with the NC group,the colon tissue of UC rats was severely damaged and ulcerated with congestion and edema,and the colonic histopathological score increased significantly(P<0.01).The serum HbH concentration decreased significantly(P<0.01),while the serum concentrations of IL-9,IL-6,and IL-1β increased(P<0.01).The protein expression of colonic ZO-1 and occludin decreased significantly(P<0.01),while the protein expression of colonic IL-9 and IL-9R increased(P<0.05).The positive co-expression levels of IL-9/PU.1 and IL-9/CD4 increased in the colon tissue(P<0.05).Compared with the UC group,the colonic mucosal structures were gradually repaired in both HM group and EA group,and healed ulcers could be observed,the colonic histopathological score decreased significantly(P<0.05).The serum concentration of HbH increased(P<0.01),while the serum concentrations of IL-9,IL-6,and IL-1β decreased(P<0.05).The protein expression levels of ZO-1 and occludin increased(P<0.05),while the protein expression levels of IL-9 and IL-9R decreased(P<0.01).The positive co-expression levels of IL-9/PU.1 and IL-9/CD4 decreased in the colon tissue(P<0.05). Conclusion:Both HM and EA can inhibit the protein expression levels of IL-9 and IL-9R in the UC colon by regulating the transcription factor PU.1,promote the repair of intestinal mucosal barrier,and down-regulate protein contents of proinflammatory factors IL-9,IL-6,and IL-1β in the serum,which may be one of the key mechanisms of acupuncture and moxibustion in reducing the inflammation of UC colonic mucosa and protecting the intestinal mucosal barrier.

Objective To investigate the clinical significances of additional chromosome abnormalities and t(15;17) in acute promyelocytic leukemia (APL). Methods A total of 90 newly diagnosed APL patients in the Affiliated Hospital of Qingdao University from January 2007 to June 2014 were analyzed retrospectively. Patients with different chromosome karyotypes were divided into four groups: additional chromosome number abnormalities group (16 cases), additional chromosome structural abnormalities group (14 cases), additional chromosome number and structural abnormalities group (4 cases) and typical chromosome group (56 cases). According to whether the patient contained t(15;17), the patients were divided into group with t (15;17) and group without t (15;17). The short-term efficacy and survival of each group were analyzed and compared. Results The rate of complete remission in additional chromosome number abnormalities group, additional chromosome structural abnormalities group, additional chromosome number and structural abnormalities group and typical t(15;17) chromosome changes group were 56.3％(9/16), 100.0％(14/14), 25.0％(1/4) and 82.1％(46/56), the early mortality rates were 25.0％(4/16), 0 (0/14), 75.0％(3/4) and 8.9％ (5/56) respectively. Among them, the additional number and structural abnormalities group had lower complete remission rate and higher early mortality rate, and compared with other groups, the differences were statistically significant (all P< 0.05). The complete remission rates of the group with t (15;17) and the group without t (15;17) were 80.5％ (66/82) and 50.0％ (4/8), respectively, and the difference was not statistically significant (P= 0.070). Conclusions APL patients with karyotypes with additional number and structural changes have low complete remission rate, high early mortality rate and poor prognosis. Patients with t(15;17)have a high rate of complete remission.

OBJECTIVE: To analyze the clinical manifestations of heart, liver and kidney damages in the early stage of COVID-19 to identify the indicators for these damages. METHODS: We analyzed the clinical features, underlying diseases, and indicators of infection in 12 patients with COVID-19 on the second day after their admission to our hospital between January 20 and February 20, 2020.The data including CK-MB, aTnI, BNP, heart rate, changes in ECG, LVEF (%), left ventricular general longitudinal strain (GLS, measured by color Doppler ultrasound) were collected.The changes of liver function biochemical indicators were dynamically reviewed.BUN, UCR, eGFR, Ccr, and UACR and the levels of MA, A1M, IGU, and TRU were recorded. RESULTS: The 12 patients included 2 severe cases, 8 common type cases, and 2 mild cases.Four of the patients presented with sinus tachycardia, ECG changes and abnormal GLS in spite of normal aTNI and LVEF; 1 patient had abnormal CKMB and BNP.On the first and third days following admission, the patients had normal ALT, AST and GGT levels.On day 7, hepatic function damage occurred in the severe cases, manifested by elevated ALT and AST levels.Abnormalities of eGFR, Ccr and UACR occurred in 8, 5 and 5 of the patients, respectively.Abnormal elevations of MA, A1M, IGU and TRU in urine protein were observed in 4, 4, 5, and 2 of the patients, respectively. CONCLUSIONS In patients with COVID-19, heart damage can be identified early by observing the GLS and new abnormalities on ECG in spite of normal aTNI and LVEF.Early liver injury is not obvious in these patients, but dynamic monitoring of the indicators of should be emplemented, especially in severe cases. In cases with normal CR and BUN, kidney damage can be detected early by calculating eGFR, Ccr and UACR and urine protein tests.

The adjacent anatomy of the pelvis is complicated, with digestive, urinary, reproductive and other organs as well as important blood vessels and nerves. Therefore, accurate resection of pelvic tumors and precise reconstruction of defects after resection are extremely difficult. The development of medical 3D printing technology provides new ideas for precise resection and personalized reconstruction of pelvic tumors. The “triune” application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis in pelvic tumor limb salvage reconstruction treatment has achieved good clinical results. However, the current lack of normative guidance standards such as preparation and application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis restricts its promotion and application. The formulation of this consensus provides normative guidance for 3D printing personalized pelvic tumor limb salvage reconstruction treatment.
